SPECIFICATION forming part of Letters Patent No. 669,589, dated March 12, 1901.

Application filed April 19, 1900. Serial No. 13,522. (No model.)

To all whom t may concern.: lower end of the intermediate section 2 is Be it known that I, CLARENCE L.

The 32 represents catches pivoted at 33 to the pendent levers 17. The office of the said catches isto engage at their inner ends the angular annular notch 34 in the collar 16, which forms the bottom of the valve-cage.

35 represents an upper collar secured to the pump-rod. Beneath the upper collar 35 and within the perforated bottom section 3 of the pump-tubing I loosely mount on the pumprod 4 an agitator-ring 36, having a lower section 38, said agitator-ring serving the purpose of stirring up the oil and sand, so as to facilitate its passage upwardly through the pump-tubing, and being limited in its upward movement bythe upper collar 35.

37 represents a stop, also on the pump-rod 4, adapted to limit the downward movement of the agitator-ring 36. The agitator-ring 36 does not move with the positive action ofthe pump-rod 4 until either the upper collar 35 comes in comtact with its upper side or the stop 37 comesin contactwith its underside, this variable motion serving to facilitate the chu ruing up or the agitating of the oil and the foreign substances contained therein. When it is desired to withdraw the valve-cage l2 for cleaning or other purposes, the pump-rod is raised until the agitatorring 36 comes in contact with the beveled inner faces 21 on the dogs l9,and said dogs being pressed outwardly withdraw the catches 32 from the angular annular notch 34 in the valve-cage, which frees the valve-cage and permits it to pass upwardly with the rod.

39 represents a ring resting upon the upper end ofthe collar 16, said ring serving as a seat for the cage-valve 24. The cage-valve 24, while not having a positive movement, as before described, facilitates the pumping of the oil over the action of a valve that is not in any manner raised or lowered by the operation of the pu mp-rod.

40 represents a plunger for pumping the oil, having a collar 41 secured to its lower end, said collar serving as a seat for an upper valve 42, having an annular shoulder 43, which seats against the collar 4l. The pumprod 4 is formed in sections, said sections being connected to each other by being screwthreaded into the upper valve 42 and lower stop 37, as shown at 44, said lower valve and stop thus serving as a coupling for sections of the pump-rod. The plunger 40 is raised by the upper valve 42 coming in contact with its lower end as the pump-rod is raised, and the plunger is depressed by means of a plunger-bracket 45, which comes in contact with the upper end ot the plunger 40, the plungerbracket 45 also serving as a coupling between two sections of the pump-rod, there being a screw-threaded hub 46 for said purpose. The position of the plunger-bracket on the upper valve and cage-valve on the upper stroke of the pump-rod before the plunger is raised is shown in Fig. I, while in Fig. III is represented the position assumed by the rod, with the plunger-bracket, upper valve, and cagevalve, when the pump-rod is in its lowest position. The lowest position of the agitatorring 36 is shown in Fig. I and its upper position in Fig. III. The position of the agitator-ring 36, lower stop 37, and pendent dogs 19 when the operating parts are being withdrawn between the dogs is shown in dotted lines in Fig. I.

I claim as my inventionl. In a device of the kind described, the combination of the pump-rod, the tubing, a cage normally secured to the tubing and a valve within the cage having fric-tional contact with the pump-rod,substantially as set forth.

2. In a device of the kind described, the combination of the tubing, a cage placed within the tn hing and normally secured thereto, a pump-rod, a valve adapted to slide on the pump-rod and spring-clamps for supporting` said valve, substantially as set fort-h.

3. In a device of the kind described, the combination of the tubing, a cage within the tubing and normally secured thereto, a pumprod, a valve adapted to operate on the pum prod, friction-clamps for supporting the valve and a link connection between said clamps 'and valve, substantially as set forth.

4. In a device of the kind described, the combination of the tubing, a sleeve secured to the tubing, levers pivoted to the sleeve, dogs on the levers having cam-faces, a cage having an annular notch and catches on the levers adapted to normally engage in said annular notch, substantially as set forth.

5. In a pump the combination of the tubing, a pump-rod, a standing valve, a housing for inclosing said valve, a valve-stop, catches in connection with the housing for normally holding the valve-stop, and arms pivoted to said catches whereby outward pressure upon the same will release said valve-stop, substantially as set forth.

6. In a device of the kind described, the combination of the tubing, a sleeve secured to the tubing, a cage within the tubing having an annular notch, levers pivoted to the sleeve, catches for engaging the annular notch, cam-faced dogs on the levers, springs IOO IIO

for normally holding the dogs in acloscd p0- CLARENCE L. PARKER.
